Abstract : The purpose of this study was to analyze the Air Force Logistic Command Depot Maintenance cost accounting systems from the viewpoint of information provided to managers. The three basic objectives of the study were: 1) Determine how the costing system treated material, labor, and overhead expenses; 2) Identify the cost information the managers had available to aid their decision process; and 3) Identify changes to the cost accounting systems from three perspectives: the Department of Defense cost requirements, the theoretical cost systems, and the managers viewpoint.
